I've managed to play the first match on the first tier today in Frost Arena. The first matchup went black after beginning the match (no coin flip animation, no loading screen, just black), I had to restart the client. I played through, and the second matchup same deal. Straight-black with no loading/info.

Anyone else getting this 100% of the time?

edit: gotten it in 75% of matches, only 1 went through ok (vs the psychotic anarchist).
